Summary: By "computing components" of this chapter, I learned the following:
Member constituting a computer relates to a variety of devices, they have their own characteristics, including speed, size and efficiency. Moreover, each of which plays an essential role in the overall process of the computer.
The computer world filled with a variety of terms and abbreviations. Speed of the processor in GHz (gigahertz) in units of memory in MB, the capacity of the external storage device in GB, places display pixel measured.
Von Neumann architecture is the underlying architecture of most of today's computers. He has five main components: a memory, an arithmetic logic unit, input devices, output devices and a control unit. Under the control unit reads the command - the core of the execution period of this process. In this period, read instructions from memory, decipher and execution of instructions.
Secondary storage devices of the computer system is critical. These devices save data when the computer is not running. Tape, disk and memory are three common secondary storage medium.
The touch screen is a peripheral device, along with input and output functions for restaurant and kiosk this particular environment. They can respond to finger or stylus on the touch screen and can determine the position of the touch screen. Existing technology touchscreen touch screen with a resistive touch screen, a capacitive touch screen, infrared touch screen and the surface acoustic wave touch screen. They have their own characteristics, suitable for different situations.
Although so far von Neumann machine is the most common, but there are other architectures. For example, some machines than one processor, parallel computing can be performed, thereby speeding the process.
